Rosewater

2066. The city of Rosewater has grown up around Wormwood, a giant alien biodome that appeared overnight in Nigeria, heals the sick once a year, and whose purpose nobody understands. Kaaro is a government agent and a 'sensitive' — one of those whose exposure to Wormwood's xenoforms grants access to the xenosphere, a vast biological data network formed from the minds of all those the alien has touched. As Kaaro investigates the mysterious deaths of other sensitives, he is forced to confront the true nature of the xenosphere — and of Wormwood itself. Winner of the Arthur C. Clarke Award. Rosewater is the first volume of the Wormwood Trilogy, a landmark of contemporary African science fiction drawing on Yoruba spiritual tradition and first-contact narrative in wholly unexpected combination.
